New
The super magnum kill springs were field tested last winter and I had great results as the springs put approximately 80 lbs of back pressure in the loop. This is a 25% improvement from the Magnum Kill Springs and very helpful when targeting big wolves.
The Shock Lock is a helpful new tool as extra lock up was required to hold all the pressure from the kill spring. Please check out the explanation of this in the product description. I stress tested these new locks in my shop and they are tough. The cable broke before the lock failed in my tests and they worked excellent in my field work so far this year.
